Abstract:
Assuming a drag function, a one-dimensional minimum-time problem is formulated for two separate cases. One case assumes an initial mass is given and the other case assumes a final mass is given. The minimum time thrust sequences for Case I and Case II are determined using Pontryagins Maximum Principle. When an optimal thrust sequence exists for both Case I and Case II to the same point velocity, distance, final mass coordinates the Case II thrusting with a coasting phase results in the minimum time. In both cases, introduction of a drag function limited the maximum attainable velocity. Finally, Case II had no optimal thrust sequences defined for initial switching occuring above an extreme velocity. Author
